Abstract

Mononitration of activated aromatic compounds using N-methyl-2-chloro-pyridinium iodide (Mukaiyama reagent)/ NaNO2/wet SiO2 reagent system under neutral, very mild and environmentally safer reaction condition has been developed. Various structurally diverse aromatic rings are subjected in this condition and the corresponding nitro-aromatic compounds are prepared in moderately high yields.

Keywords: Aromatic compounds, mukaiyama reagent, N-methyl-2-chloropyridinium iodide, nitration, sodium nitrite.
